iNrEncHANGnABLE SANDER.

Application filed March 1, 1924. Serial No. 696,368.

T all whom t may concern.'

Be it known that I, WILLIAM H. BUGKING- HAM, a citizen of the United States, residing at Mayiield, in the county of Lackawanna and State' of Pennsylvania, have invented a new and useful Interchangeable Sander, of which the following is a speciiication.

My invention relates to sanders wheeled vehicles.

Although my improvements are applicable to any type of vehicles-such as steam or electric locomotives, I will describe it (for purposes illustrative of its use) as applied to a steam locomotive.

All locomotives carry a sand box generally in a dome on the top or' the boiler trom which a pipe -is connected and leads down to a point above both rails immediately above and in front of or between the drivers on each side of the locomotive. Most all of these sanding devices are provided with suitable devices ior inducing and controlling the flow of sand to the tracks.

The Sanders at present in use are provided with steam or air jetting devices for atomizing or breaking up the packing of san-d aud vfurnishing to the track the desired quantity of sand to provide the approximate degree of grip ol2 the driving wheels' upon the road bed.

This blowing of the sand in the sander, acts, through the cutting quality of the sand. to wear out the walls of the inner shell of the sander. This serious objection I have obviated and I have produced a sander which will last twice as long as those now in use. Furthermore my improved sander is capable of more flexible installation in adapting it to various types of wheeled vehicles at present in use, owing to the fact that it can be installed either side up.

The drawings which serve here to exemplity one way of carrying out my invention are- Figure l a central vertical sectional view of my sander.

Figure 2, an end view ot the same.

In the drawings-1 represents the body ot' the sander. 2 is the diagonal main passage or chamber.

3 is the receiving passage to the upper end 4, from which a pipe leads to the sand dome o'l the locomotive above, and is connected with the lower end of the main chamber 2.

5 is a vertical passage which leads into Jfor the upper end of the chamber 2 and connects with the pipe which leads to a point directly above the railroad track.

6 is the jet nozzle connecting with a fluid pipe 7 leading to a source ot' fluid supply (such as air or steam) under pressure tor blowing or atomizing the sand in the sander and discharging it into the discharge passage even if the sand in the sander has packed or is lumpy.

8 is a removable plug which carries the jet nozzle G at the lower end ot the chamber 2. 9 is a plug similar to the plug 8 closing the upper end of chamber 2 and interchangeable therewith. A convenient diameter for these plugs is an inch and a quarter. Laterally of each passage 3 and 5 I insert removable plugs 10 of say three quarters of an inch, which are interchangeable and which serve as clean outs.

My sander when installed receives the sand from the dome into passage 3 and chamber 2. Upon the opening of the fluid jet 6 the sand is disintegrated and sprayed upwardly into the top ot the chamber 2, and falls lightly and evenly down through passage. 5 to the track.

These sanders as heretofore made do not give very long service, because the sand blasts induced therein wear out the interior of the sander. To prolong the life of the sander I have made it reversible. It will be noted that the sander may be reversed or simply turned end for end, and the interchangeable plugs 8 and 9 reversed, whereupon the sander operates precisely as it did before.

A convenient size for into passage 3 and out of passage 5 inch which is standard for this service.

In order to prevent the possibility o'l any clogging up of the discharge passages 3 or 5, I may introduce an auxiliary jet 1 1 or 12, or both, into these passages. For this purpose the `fluid pipe 7 may be tapped at 13 and pipes lai and brought into communication with the jets i1 and 12.

As a matter of practice it will probably be preferable to use simply the auxiliary sys-- tem 10, 12. and i/-l in the passage 5 leading from the sander to the track, the corresponding opening in passage 3 shown in the drawing as being occupied by bushing plug lO being plugged with a usual plug similar the pipes that lead is one to' plug 9 and the jet ll and pipe l5 resage therethrough, vertical passages leading nioved. f from each end of the diagonal passage, and

In reversing' the device the auxiliary jet .interchangeable plugs at each end of the 10 is correspondingly changed. diagonal passage one of Which contains a 5 I claim` jet nozzle whereby the sander may be rever An interchangeable reversible sand trap sibly installed. comprising a housing having a diagonal pas- WILLIAM I-I.
